Hi guys,
I have a odd question i suppose.

I have a bunch of routers all talking OSPF to each other. Sometimes our carrier buggers the connection and OSPF goes down ( But vanishes from SNMP ) so cant use that to poss if a link is down.

The interface stays UP UP as its ethernet and its local link is actually up anyway.

Is there some way i could so summat like.

Router1
Int gig0/1
monitor SOMENAME1

Router2
Int gig0/1
monitor SOMENAME1


Lets say both routers would now poll the other end for SOMENAME1 , If it replys then lets say the MONITOR SOMENAME1 value would be up.

If it didnt then its value would be down.

Is there anythin like this?

I know of a few protocols but they all seem to shutdown the link on failure. I just need some SNMP value to change if the other end of the link is unreachable.



Thanks
L
